摘要:
A printing device includes a supply of colorant that is non-refillable from an end user perspective and that is at least substantially non-removable from the printing device from the end user perspective. The printing device also includes a printing mechanism that forms images on media using the supply of colorant.

An ink delivery regulation apparatus includes a support configured to be positioned within an ink chamber and a resilient deflection member coupled to the support. The resilient deflection member is configured to resiliently deflect from a generally concave shape to a generally convex shape in response to a change in said negative pressure.

A fluid containment structure includes a containment vessel having an interior vessel space for fluid containment, and a fluid outlet communicating with the interior vessel space. A flexible bag with opposed side surfaces is disposed within the containment vessel, vented to an external atmosphere outside the containment vessel. A sacrificial bond structure is formed between the side surfaces, and restrains the side surfaces together until a back-pressure within the vessel space exerts sufficient force to break the sacrificial bond structure, allowing air from the external atmosphere to enter the bag and enlarge an interior bag space.

An embodiment of the invention relates to a method including determining when a print button widget on a webpage has been accessed by a user from a communication device accessing the webpage, recording an identity of an online publisher hosting or maintaining the webpage, issuing a print instruction to the communication device for the communication device to create a print job when the print button widget has been accessed by the user, identifying at least one detail of the print job, sending a notification and the at least one detail of the print job to an exchange server, and sharing an online publisher report including the at least one detail of the print job with at least one advertiser
摘要:
A replaceable ink supply comprises an ink container with an internal chamber formed from a plurality of walls. An ink reservoir block can be located within the internal chamber. Further, a channel can be formed in at least one wall of the internal chamber and the channel having an open side exposing a portion of the ink reservoir block.

Ink reservoirs and methods are provided. One ink reservoir has at least one compartment and first and second vents that communicatively couple the compartment to an atmosphere surrounding an exterior of the ink reservoir.

A high efficiency, liquid supply vessel is provided. The liquid supply vessel includes a chamber, either an open-foam or septum-based fluidic interconnect, a tower, and at least one gas-permeable vent. The tower includes a valve which remains closed when the vessel is inserted into a printer and the fluidic interconnect is engaged, thereby retaining the liquid in the vessel. When the printhead is operated, a sufficient vacuum is created to open the valve, thereby supplying the liquid to the printhead. Whereas the vacuum pressure may otherwise rise to unacceptable levels, the gas-permeable vent enables the pressure to be equalized. Similarly, the vent equalizes pressure during altitude and/or temperature changes, thereby preventing pressure increases or decreases which would otherwise be associated with such changes.

A disposable/refillable inkjet cartridge with bubble generator and an adhesively attached bubble generator vent cover. The cartridge is filed through a bubble generator opening in the cartridge bottom eliminating a separate filling orifice and easing the priming operation. The vent cover is adhesively attached making removal for refilling easier and avoiding suspected problems related to welding flash in welded vent covers. The bubble generator includes a tapered opening which receives a ball. The ball contacts ribs extending longitudinally along a tapered portion of the opening. The ribs are spaced over an arc of the opening. A bubble forms as needed between the ball and opening to maintain back pressure. The ribs and taper produce more consistent bubble pressures. A single piece of tape over the bubble generator and printhead nozzles avoids common causes for depriming.

An ink delivery apparatus includes a pressure tuned rolling piston having a distal end. The distal end includes a pressure responsive portion. A first convolute portion supports the pressure responsive portion, and the first convolute portion is configured to provide a first level of resistance against a negative pressure.
